Running into a compilation error when trying to import agent-rs crate. Not seeing the same error from a barebones Axum project. Thoughts?

[saikatdas0790]

I am trying to use this crate in an SSR'd cargo-leptos project:
https://crates.io/crates/ic-agent

It seems to work fine with a barebones axum project. Here is a minimal reproduction:
https://github.com/saikatdas0790/minimal_reproduction_import_agent_rs_in_axum_project

Try cloning and cargo run. It boots without any errors.

But if doing the same import in a cargo-leptos project, running into the following errors.

Minimal reproduction here:

I'm unsure if the issue is with the crate or cargo-leptos.

Thoughts?

Is it failing while trying to compile it for WASM? i.e,. have you tried making it optional and only enabling it for SSR?

[saikatdas0790]

That's the thing. I haven't imported this crate into any code yet with a use statement.

This is simply after adding it as a dependency and running cargo-leptos watch.

Let me try that though.

Correct. cargo builds all your dependencies for any given target before it begins building your application code, not after it detects a use statement in your application code.

This was solved by setting a feature flag in the imported crate.
